CORRUGATED ROLLER.

Application filed January 26, 1920.

Z '0 all whom it may concem:

Be it known that I, FREDERICK D. VViLsoN, a citizen of the United States, residing at doline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Corrugated Rollers, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to rollers employed in elevating mechanisms, and over which a belt is adapted to travel by rotation of the roller, and the object of my invention is to provide a roller as a new article of manufae ture which will be more efficient than the round smooth rollers ordinarily used, and which will be economical in construction and operation.

Referring to the drawings in which similar numerals indicate identical parts Figure l is a side view of my improved roller in part section, and Figure 2 is an end View.

The roller body 1 is of uniform diameter throughout its length and is constructed of corrugated sheet metal with the corrugations longitudinally disposed and of equal depth from end to end, and the longitudinal edges of the metal lap welded at 2 or otherwise secured together in any desired manner. In the ends of the hollow cylinder thus formed are identical castings 3 having their peidpheries corrugated to fit snugly within the cylinder or roller body 1. The-peripheral surfaces of the castings 3 are beveled, as shown at a in Figure l, for approximately one half their widths to ensure an easy insertion in the end of the cylinder 1, the remainder of the surfaces fitting tightly Within the roller body. Perforations 5 are made in the periphery of each of the castings 3 and. when the latter are placed in the ends of the cylinder 1 th metal of the cylinder, immediately over the perforations, is punched or upset into the perforations, as shown, to

hold the castings 3 firmly in place. Each of the castings 3 is provided with a gudgeon 6 Serial No. 354,31 1.

rigidly held in the hub 7 by a pin 8 which passes through suitable openings in the hub 7 and the gudgeon 6, the latter projecting beyond the end of. the cylinder 1 and providing means by which the roller can be suitably supported.

lVhat I claim is- 1. As a new article of manufacture, a hollow roller formed of sheet metal and having a surface of longitudinally disposed corrugations, av casting in each end of said roller, each casting having its periphery corrugated, and means to secure the castings in'position.

2. As a new article of manufacture, a hollow roller formed of sheet metal having a surface of longitudinally disposed corrugations, a casting in each end of said roller, each casting and beveled in one direction, and means to secure the castingsin position.

3. As a new article of manufacture, a hollow roller formed of sheet metal having a surface of longitudinally disposed corruga- .tions, a casting in each end of said roller,

each casting having one or more perforations in its periphery and held in position by forcing the metal of the roller into said perporations.

4. As a new article of low roller formed of surface of longitudinally disposed corrugamanufacture, a holtions, a casting in each end of said roller;

each casting having its periphery corrugated and beveled in one direction, said castings having one or more perforations in the peripheries thereof and held in position by forcing the metal of the roller into said perforations.

As a new article of manufacture, a hollow roller formed of sheet metal having a surface of longitudinally disposed corrugations, a casting in each end of said roller, each casting having its periphery corrugated,

means to secure the castings in position, and

supporting means on each casting.
